Reduce driveline vibration on lifted vehicles with this Heavy Duty Slip-Yoke Eliminator Kit for Jeep's NP231J transfer case. Transfer case tailshaft length is reduced by 6.5" on '97-'01 Wranglers and 4.25" on '88-'95 models resulting in improved driveline angles. Kit includes a redesigned transfer case mainshaft which is not only shorter but has an 18% larger spline diameter, a 54% increase in torque capacity.

Comments: I put this on after having to replace my u-joints after 4000 miles, it cost about $700 for this and the driveshaft. although it was an expensive mod, it was well worth it, the jeep drives like a caddy now

Comments: Easiest install ever. Most difficult part is getting that damn harmonic damper off the stock housing. Very satisfied with the results. Ordered from Tom Woods with double cardan CV driveshaft. Rides excelent.

Comments: The installation was easy, especially for my first time to ever break into a transfer case. Instructions where straight forward, only thing I recommend is having an AIR compressor. Would make things a TON easier, but AIR will help on most things.
